Hey, how's it going, I have Alpine Type S 6x9's mounted in the back off my car, and all that had to be done was shave a SMALL portion of the metal away ... it depends what 6x9's you buy, some have small magnets, others, like the Type R's have a huge magnet and needs more cutting ... I'll put up photo's soon - well, as soon as I get my damn camera back :
Smeags ...
